To all whom it may concern.'

Be it known that I, HERBERT J. REEVES, a citizen of the United States of America, and resident of the borough of Manhattan,

city, county, and State ofNew York, have invented certain new and useful Improvements in Sprinkler-Nozzles, of which the following is a specification.

My invention relates to sprinkler nozzles of that type particularly adapted for spraying and irrigation purposes and the object of the invention is to produce such a device wherein the spray will be evenly distributed in the form 0f either a fine mist or heavy shower or in any intermediate condition, without employing any revolving parts.

In the following I have described, in con` nection with the accompanying drawings, several forms of device illustrating my invention and modifications thereof.

In the drawings Figure l is an elevation lshowing one form of device; Fig. 2 is a vertical sectional view of the form of device shown in Fig. l; Fig. 3 is an elevation, partly in section, illustrating a means of varying the spread of the water or other fluid; Fig. 4 is an elevation of a form showing in connection therewitlra device for limiting the throw of spray to a certain direction; Fig. 5 is a view of the device shown in Fig. 4, partly in vertical section; Fig. 6 is a plan view of the limiting device; Fig. 7 is a cross sectional view of the device shown in Fig. 5; and Fig. 8 is a plan View of a detail of construction.

Similar letters of reference indicate simi lar parts throughout the several views.

a indicates the base of the `nozzle internally screw-threaded for connection to a suitable pipe or hose. The exterior of base ais shown as being roughened to provide for frictional engagement to adjust it on the pipe or hose. The top of base a is provided with a perforated plate b, which may be either a separate piece or formed integrally with the base, the plate b forming a support for screw-threaded stem o wh1ch may be pinned in a socket d carried by plate b or otherwise mounted thereon. The perforations of plate b form means whereby the fluid carried through the nozzle may be freely passed therethrough. e indicates a tapering cap, open at the top and adapted to be engaged with base a by screw-threaded or other suitable means. f indicates a spreader .in substantially the form of an inverted truncated cone having an outwardly concavely curved configuration, and adapted to screw-threaded engagement with stem c.

is a lock-nut for holding spreader f in ad(Z justed position on stem c. In Fig. 3 the cap e is shown as having a greater taper and a smaller opening than the corresponding cap e in Fig. 2 and the spreader f is also shown as having a reater taper than the corresponding sprea er in Fig. 2.

In operation the fluid, under pressure, passes through the nozzle, strikes against the spreader and is deflected a greater or less distance according to the pressure, the shape or angle of taper of the spreader, the distance of the spreader from the top of the cap and the size of the opening in the top of the cap. The fluid is also directed more or less horizontally or vertically according to the shape or angle of taper 0f the spreader, the distance of the spreader from the top of thev cap and the size of the opening in the cap. The size of the drops of flu1d sprayed is adjusted by varying the distance of the spreader from the top of the cap. The rategof discharge of fluid per unit of time is also adjusted by varying the size of opening in the top of the cap and the distance of the spreader from the top of the cap.

The form of device shown in Fig. 2 will throw the fluid a greater distance than the form shown in Fig. 3 because of the angle of taper of the spreader while the form shown in Fig. 3 will`throw the fluid higher and in a finer spray than that shown in Fig. 2.' When the spray is to be thrown higher it is desirable to have it finer and therefore the cap with the smaller opening and the spreader with the greater angle of taper should then be used, the adjustment of spreader to opening also regulating the sizeof the drops from drops or even a sheet scribed, I have provided a bushin 'means of the device s own lin connection with Figs. 4 to 6 inclusive. y In the form of device shown in these viigures, in addition to the parts heretofore deh carrying a shield or plug piece z'. Th ushing is shown as internally screw-threaded to coact with the externally screw-threaded neck j of cap e and as being located between the ca e and spreader f. As illustrated the shleld z' covers approximately one-third of the opening at the to of the cap and is provided w1th forwardly projecting, defiecting win s lc, k, merging into the downward taper o spreader f. The top of the shield z' is cut away to receive and form a seat for the spreader. As shown the device will throw the liquid over an area of approximately 180, the s reader being seated against the shield. he shield may be adjusted relative to the ca so that the spreader mayV also be a justed relative to the cap as described in connection with Figs. 1 to 8. The spreader and shield may also be adjusted relative to each other, so that by leaving a space between them the Huid may be thrown thefull distance, say 20 feet, on one side and any desired distance less than 20 feet, say 4: feet, on the other side. In other words', the provision of a shield such as I have described enables the operator to control the area and found vin sprinkler or spray devices in that it has been impossible to cover a desired area wlthout also covering the adjacent area which it was not desired -to irrigate orv do not restrict myself to any particular use of. the device nor toany particular constructlon of the parts thereof, further than the scope of the appended claim demands.

The base is enerally designed as of a standard' size w ile the caps and spreaders may be of various shapes and interchangeable for the effecting of the particular purpose in hand. It is to be understood that the device may belused in any position, horizontally, at an angle or inverted as desired. The edges of the spreaders, sields and lock nuts are shown as roughene ment or removal. Thevarrows in the several figures show the direction of the fluid assumed to be passing therethrough.

.A sprayer nozzle comprising a base, a cap mounted thereon, a spreader adjustable toward and away from the cap and having a downwardly tapering configuration, and a shield for closing a portion of the opening between the cap and the spreader, the shield being provided with forwardly projecting, deflectlng wings adapted to merge into the downward taper of the spreader. In testimony whereof I have signed-this specification in the presence of two subscribing witnesses.
